My great, great uncle Robert F. McKee, Sr., was a design engineer at Baldwin Locomotive Works and he would give my father different Baldwin Locomotive builder's cards when my father would visit him in Collingswood, New Jersey. Here is a beautiful engine he helped design, the T-1 class 4-8-4 for the Lehigh Valley Railroad. Note the side rod on the back tender truck. This Baldwin Locomotive Works builders photo card is from the John R. Doughty collection.
